Use cases & applications
High-Precision Filtration for Sensitive Equipment
In environments where downstream equipment like pneumatic controls or instrumentation requires ultra-clean air, the 0.01 µm borosilicate glass fibre media captures sub-micron particles and oil mist. This protects sensitive components from contamination, reducing maintenance costs and downtime.
Continuous-Duty Compressor Stations
For compressor stations running 24/7, this filter's low differential pressure of 80 mbar minimizes energy loss while maintaining high filtration efficiency. Its robust construction ensures consistent performance under continuous load, extending service intervals.
Harsh Temperature Environments
Operating reliably between 1.5 °C and 65 °C, this filter suits applications in unheated warehouses or outdoor installations. The borosilicate media resists moisture and thermal degradation, ensuring stable filtration even with temperature fluctuations.
Space-Constrained Installations
With a total height of 165 mm and outer diameter of 61 mm, this compact filter fits easily into tight spaces on machinery skids or in crowded filter banks. Its lightweight 0.19 kg design simplifies handling during replacement.
Frequently asked questions
How do I confirm this filter fits my specific compressor model?
Check your current filter's outer diameter (61 mm), smallest inner diameter (27 mm), and total height (165 mm). If these match, this filter is a direct replacement. It is compatible with equipment from Atlas Copco, Ceccato, and Mark, but we recommend verifying dimensions against your existing filter.
What is the filtration rating and media type?
This filter uses borosilicate micro glass fibre media with a filtration rating of 0.01 µm. This provides high-efficiency removal of solid particulates and oil aerosols down to 0.01 microns.
What are the key dimensions and thread type?
The filter has an outer diameter of 61 mm, smallest inner diameter of 27 mm, body height of 155 mm, and total height of 165 mm. Thread specifications are not provided; please consult your equipment manual or measure your existing filter's threads.
Is this an OEM or genuine part?
This is an aftermarket replacement filter built to the original dimensions and ratings. It is not a genuine or OEM part but offers a cost-effective alternative with the same performance characteristics.
How often should I replace this filter?
Replacement intervals depend on operating conditions and air quality. Monitor differential pressure; when it exceeds 80 mbar or as recommended by your equipment manufacturer, replace the filter. Regular inspection ensures optimal performance.
